Leave the motorway at Lannemezan.
The direction is Spain by tunnel Arragnouet-Bielsa.
6 km after Arreau, and after Guchen, there is a bridge.
500 m after this bridge is Guchan, the village is on the left.
You can turn on the left and go to the place of the village, in front of the "Mairie".
Then we shall meet you there.
